The invention relates to newand useful: 1mrovements m can closin machines and more particularly to a-can closing machine having a plurality'of closing stations which are moving continuouslyand which receive, the can bodies one after another, with the ends asso;

ciated therewith,gand join the ends to the can body during the travel of the closing stations, so that the cans are received, closed and eject ed duringa single rotation of the machine.

In amachine of the above type, the closing stations are necessarily spaced from each other so as, to provide room for the parts which cooperate in the securing of the can end to the can body. It is desirable, however, that the seaming stations shall be relatively close together, and shalltravel in a relatively small circular path. 7 I

An object of the invention is to provide a closing machine wherein the can to be closed is rotated by cooperating rotating chucks, and

the can end is secured to the can body by seaming rolls associated with the chucks and bodily traveling therewith, and wherein the actuating mechanism for' the" seaming rolls travels'bodily with the chucks, and the supporting spindles on which theseaining'rolls are mounted are located outside of theibodily path'of travel of the axes of the chucks, thus permitting the chucks to be placed relatively close to the center about which the seaming stations travel. l

Another object oi the invention is to provide a machine of the above type wherein the seaming rolls are alternately moved into con tact with the flange on'the can end for form-- 'ing the double seam by cams which rotate about a sleeve supporting theupper chuck, and at a different speed than thefrotat on of :the chuck.

. A still further object .of the invention is to provide-a machine of the above type having a supporting base on which a lower ,frame'is mounted, outersupporting columns carried by the lower frame, and an upper fr I I l t vious and will ,in partbe herelnafter o mounted on said supporting columns, with a,

rotating turret located within said rotating columns ,on which the rotating chucks and A still further object of the invention is to provide a machine of the above type with an upper rotating turret carrying the rotating chucks and the seaming rolls, and also a lower rotating turret carrying cooperating rotating chucks for the cans to be closed, which machine is also provided with means whereby said upper turretmay be raised and lowered in said frame for operating upon' cans of difi'erent heights.

A still further object of the invention is to provide a machine oi? the above type with means whereby the upper otating turret m y be adjusted a gularly relative to the lower rotating turret for-alining the axes ofthe co operat ng upper and lower. chucks. A still further object of the invention is to provide a machine of the above type with means for raising the lower chuck to clamp the can againstthe upper chuck, which includes toggle levers movable to a point slight- 3 1y past dead center when the can is clamped by the chucks,- so that the toggles operate to hold the can chucked independent of the action in the rotation of the turret for the purpose of releasing a can between the'first and second operations thereon.

A still further object of the invention is to provide a machine of the above type wherein a center rotating spindle operates to rotate both. the upper and lower chucks, so that the timing of the cooperating chucks is maintained.

A still'further object of the invention to provide a machine of the above type wherein the means for rotating the turrets includes a multiple disk clutch, so that in case of a jam,

The invention is directed broadly to a closing machine for cans, and more particularly to a closing machine for closing a filled can. The machine includes a plurality of seaming stations which travel continuously about a fixed center. The can bodies, together with the can ends therefor, are fed to the seaming stations while they are traveling. A support ing base carries the lower frame, on which are mounted three supporting columns, and

these columns carry at the upper ends thereof, an upper frame. Supported on the lower frame is a lower turret which rot-ates on suitable ball bearings on the lower frame. In the center of the machine there is a rotating spindle, and surrounding this rotating spindle, is a sleeve. The sleeve is keyed to the lower turret and is supported by means whereby the sleeve may be raised and lowered. Secured to the upper end of the sleeve is the upper turret, and said upper turret is secured to said sleeve so that the angular position of the upper turret may be adjusted relative to the lower turret. The turrets are rotated by a sleeve shaft mounted in the upper frame. This sleeve shaft is connected to the upper turret so as to rotate the upper turret, and the upper turrent, through the sleeve surrounding the central spindle, ro-

tates the'lower turret. The upper turret is connected to the rotating sleeve shaft in such a way that it may be raised and lowered, so that the turrets are properly positioned for the height of can desired to be closed. Mounted on the upper turret is a series of chucks, and these chucks are rotated through a geared connection with the central spindle, and the central spindle is driven from the main shaft. Mounted in the lower turret are a series of chucks, one for each upper chuck, and these upper and lower chucks are in axial alinement, and cooperate to chuck the can during the closing of the same. The lower chucks are raised and lowered by suitable toggle levers which move to a point slightly beyond dead center, so that the toggle lever lever holds the chuck raised. Associated with each pair of cooperating chucks are seaming rolls for performing the first and second seaming operations. These seaming rolls are mounted on levers Journaled 1n the upper turret,

and the seaming rolls are so positioned as to travel bodily in a path outside of the axes of the chuck spindles, and well in toward the center of rotation of the turrets. The seaming rolls are moved into contact with the flange on the can end by cams which rotate about the axes of the chuck spindles, and these cams are driven by a stationary gear attached to the upper frame of the machine.

By placing the chuckss relatively close together, the distance between the cans during closing is comparatively small, and therefore, a can does not need to'be accelerated to 'agreat extent when it is fed into the machine from a. filling machine in order to properly space the cans for the closing machine. Furthermore, the cans travel in a' circular path, the

/ 10 diameter ofwhich is comparatively small,

and this. aids materially'in preventing the spilling of the contents of the-cans duringclosing; The can bodies -and can ends are assembled in the assembling turret and are delivered thereby to the closing stations as they pass the take-in point. After the can is closed, which occurs during a partial rotation Ofthe closing machine, a take-away arm removes the closed can from the seaming. stabracket arm is a column 4, and on the upper ends of these columns, is supported the upper frame 5 of the machine. Mounted centrally of the columns is a rotating spindle 6. SurroundingQthis spindle 6 is a sleeve 8 which is rotated independently of the spindle. This sleeve 8 carries the upper turret 9 at its upper portion,and the turret is rigidly, but adjustably secured to. the sleeve, and rotates therewith, Surrounding the. sleeve is a lowerturret 10 which is keyed to the sleeve and rotates therewith, but the sleeve is free to slideup and down in said lower turret for adjusting the machine so as to operate upon cans of different heights. The lowerturret is mounted on the lower frame 2. Said lower turret rests on suitable ball bearings 11 carried by said frame. The sleeve 8 is provided with a suitable threaded section 12, and a threaded collar 13 engages the threaded section of the sleeve and supports said sleeve. This threaded collar 13 is located between members 14 and 15 which are in turn secured to short sleeve section 7 which has a telescoping or sliding connection with the lower end of the sleeve 8. The members 14 and 15 and the sleeve section 7 are keyed to the sleeve 8 soas to rotate therewith. The lower member 14 is mo unted on ball bearings 14, and this serves as a supporting means for the sleeve 8. The threaded collar 13 is provided I l with a spiral gear which meshes with a worm gear on the shaft 16. By turning the shaft 16, the threaded collar is rotated, and this raises or lowers the sleeve 8 .in'the sleeve section 7 Thus-it is that the upper turretis raised or lowered relative toth'e lower turret, while the lower turret is mounted so as to rotate on ball bearings on the lower frame of the machine; I

Mounted to rotate on the frame 5 is a sleeve shaft 18. This sleeve shaft 18 is mounted in suitable bearings in a depending bracket 19 carried by the upperframe' 5. A spiral gear 20 is rigidly secured to the sleeve shaft and this spiral gear 20 meshes with a worm gear 21 carried by a cross shaft 22. A spur gear 23 is freely mounted on this cross shaft, and this spur gear meshes with a similar spur gear 24 mounted on the end of the main driving shaft 25 (see Fig. 2).

- As noted above, the spur-gear 23 is'freely mounted ontheshaft22,butisconnectedthereto by means of. a multiple disk clutch. as

ries of clutch disks 124 and .125. The clutch disk 124 and the clutch disk 125 are alter nately arranged, and each one of the clutch disks 124 are secured to the hub 23 of the gear 23. Said hub is provided with longitudinal recesses 23", and each of these disks 124 has an inner radial rib 23 fitting in these longitudinal recesses. Thus it is that these disks 124 are keyed to the hub 23. The member 123 is provided with an overhanging flange 126. .Each of the disks 125 is provided with recesses 125 which engage ribs 126 carried by this overhanging flange 126. Thus it is that the disks 125 are all keyed to themember 123, and this member 123 is keyed to the shaft 22. A spring 127 bears at one end against the member 123 and at its other end against an adjustable collar 128 threaded on to the end of the shaft 22. This springnormally forces the clutch disks into frictional engagement with each other. By adjusting the threaded collar 128, the frictional grip of the clutch disks can be varied.

The main driving shaft 25 is mounted in suitable hearings on the upper frame and is operated by a cone clutch member 26 which is keyed thereto. This clutch member is adapted to .be connected to a belt wheel 27 through a clutch operating mechanism which includes a yoke 28, a link 29 attached thereto, and a lever 30 pivoted at 31 to the upper frame member (see Fig. 1). This lever 30 is adapted to be actuated by a hand lever 32 which is pivoted at 33 to the center of the ma-- chine. The lever carries an arm 34 which is connected to the lever 30, so that when the lever 32 is oscillated, it will actuate the yoke member 28, and move the friction driving wheel 35 into engagement with the inner friction "surface of the belt wheel 27. The rotating movements of the shaft 25 are imparted through the means described, to the sleeve 9. Thus it is that the sleeve 18 causes the,

upper turret to rotate. The upper turret causes the sleeve 8 to rotate, and the sleeve 8 causes the .lowe'rturretio rotate When the upper turret is raised to a'difierent set position for operating. upon a can of a different height, these rods 36 slide up or down in the recesses with which they are associ ated, so that the turreticanbe raised and low I eredwithout disturbing the driving connection therefor. f

.Mounted in the upper turrent is'a upper chucks 37, one for each seaming station. Each chuck 37 is mountedon a chuck sleeve 38, and this chuck sleeve is in turn mounted in a suitable beariiig located in a space provided therefor in the upper turret. The bearing for the chuck is held in its proper position relati\'e,-.to the turret by a bracket bolted to the side face of the turret. One of these bracketsis shown at 44 in Fig. 5, and the bracket is secured to the body of the tur ret by bolts 45. The chuck. is held from endwise movement by a ball thrust bearing 38. At the upper end of the chuck sleeve '38 there is a spur gear 39, and the spur gears of the several chuck sleeves mesh with a common central'spur'gear 40 which is fixed to the central spindle 6. Thus it is that the rotations of thespindlefi' are imparted/ to the upper chucks. g ,4

ooperating with the upper chucks 37 are lower chucks 92; These lower chucks form the support for the filled can, andqthe lower chucks are raised so as toclampthe can end i and filled can against the upper chuck, and

then the two chucks'together, rotate the can for causing the seaming-rolls to form a double seam. The lower 'chuck members 92 have to be raisedand lowered aswell as rotated. 40 These chucks 92 are'secu'red to a sleeve 93 Fthat both of the upper-and-lower chucks are positively rotated and are rotated in timing with each other. The pinion 97 is attached to asleeve 93 'whi'chis keyed to the lower end ofthe spindle 6, and=this sleeve 98 is flinounted for free rotation in a bushing carriedby the sleeve 8. I

4 The sleeve 93 is mounted in a suitable bushing 99 located in a pocket in the lower turso. ret 10. Thege'ar'teeth 96 prevent the gear sleeve from inoving endwise in one direction in the bushing, and a collar 100 secured to the upper endi of the sleeve gear prevents said sleeve gear from moving in the o posite direct10n in said bushing. Locate centrally series of ,view in Fig. 10.

from the operating cams for the toggle memcam has a detachable section 139 which is held in lace by ascrew 140 and locating pins .141. T is is for the purposeto aid in the of the sleeve 93 is a' plun ger 101. This plun- I ger *101 carries a supporting head 102 at the upper end thereof; The head is threaded on *to the plunger and can be adjusted on the plimgen A bolt 103 secures the head to the plunger in adjusted positions. Located betweenthe' plunger head and the" chuck 92 is a'ball cage 104, so that the chuck 92 is supported by the plunger and rotates freely thereon. The sleeve 93, of course, rotates about the plunger with the chuck 92. 'Secured-to the lower end of the plunger 101 are toggle levers consisting of a member 105 which'is pivoted to the plunger, and a memher 106 which is mounted to oscillate on a supporting shaft 107. The two members are secured together by-a pivot bolt 129. The member 106 has a segmental rack 130 which meshes with a rack bar 131. This rack bar right angles to the axis of the shaft 107 in a suitable T-sha ed guideway formed in a bracket 132 carried bythe lower turret 10. This 'rack bar 131 carries a roller 133, which runs in a-cam groove 134 in a stationary cam 135. This. stationary cam is shown in plan baid cam roove has a concentric portion 136 of one ra 'al diameter, and a concentric portion 137 of a less radial: diameter, and as the roller passes from one portion of the cam groove to the other,"'it will move the rack bar 131 radially of the machine, and this will move the toggle members to and from alinement. As the toggle membersmove into alinement, the lower chuck will be raised, aiid wherl they move out of alinement then the, lowerchuck will be lowered. These toggle members move slightly by dead center, and their movement is limited by a shoulder 138 on the upper toggle member engagin a shoulder on the lower'toggle member. he purpose of haviiig the toggle members move to a point heyond-dead center, is to take the strain off bers. In other words, the cams will move no the toggle members so as to raise the lower chuck, and clamp the can against the upper chuck, and when the can is clamped for roe tation, the toggles are positioned slightly by dead center, and it is the position of the toggle members which holds the chuck-elevated. The stationary cam 135 is secured to the lower frame member 2. This stationary assembling of the parts. The stationary cam v 135 is provided with a cut=away portion'142 in the outer wall'thereof, and a recess 143 333 in the inner wall thereof. Associated with which can be' moved into the cut-away pofr-= tion of the cam. The purpose of this handoperated device 1s for moving the rack bar -to. release thelower. chuck between the first andsecond operations of the seaming rolls. It will readily be seen that if the rack ban is stopped opposite the pin 146, when the lever is pulled out at its free end, the pin 146 wil'lengage the roller .183 and .will move the roller radially inwardly into the recess 143, and this inward movement of the roller and the. rack bar attached thereto, is suflicient torelease the toggle levers which support the lower chucks.

A bevel gear 42 is mounted on the upper end of this spindle 6, and this bevel gear 42 meshes with a bevel gear 43 carried by the main driving shaft 25. The main driving. shaft, therefore, .not only rotates the upper turret, but'also rotates all of the chuck spindles, the turret being rotated through the sleeve shaft 18, and the chuck spindles through the spindle '6. F urther-- more, it will be noted that the spiral gear 20,

is of relatively large diameter, and therefore,

the turret will rotate'at a much slower speed than the chuck spindles.

The means'for supportingand dperating the seaming rolls is .shown"more particularly in Figures 3, 5, 5 6, 7, 8 and 9/ The bracket 44 is provided' witha bearing sleeve 46 in which is. mounted a spindle 47. Thisspindle .carries ,a first Iop'eration roll "48.. Also' mounted in this bracket isa bearingsleeve 49 for the spindle 50 which carries a second operation roll 51. 'Qnthe upper. end of'each spindlethere is a bracket member52. Each bracket member is'v provided with a cam roll v53. The bracket member 52 carries an adjusting worm gear 54.". Eaoh'spindle is provided with arectangular section 55 adjacentthe upper end thereof, and mounted om this rectangularsection'of the spindle is a segment sleeve'56 which has an yapeningthe'rethrough fitting the rectangular sect-i611 of the at their lower ends with a crank arm 58.

Mounted in this crankarm isashortshaft 59- i .on whichjthe seaming roll is mounted. It is understood that the .second operation roll 51 is mounted onthe spindle 50, while the first o eration roll' 48 is mounted on the spindle y The shaft 59 is held in the crankarm of the spindle 50 bya set screw 60.. This is true ofv the first operation roll as well. -It.is.

It is understood that there is a similar bracket'memher 52 and adjusting the spindle 47 carrying the first operation worm gear 54 for this spindle 47 which carries the first operation roll 48. Thecam roll 53- is adapted "to bear against the cam 65, while the cam roll 53 bears/against a cam 66.; Springs 67, one for each bracket-member attachedto the'spindles carrying the 1. seamingrolls, arelocatedbetween said bracket members and the face of the turret, as shown in Fig. 3.; These springs operate to hold the cam rolls .in contact with thefcams.

These cams 65 and 66 are. carried sleeve 68, and the sleeve is mounted to rotate freely on a cylindrical bearing on the bracket 69 which *isremovably secured to the bracket 44 by bolts 69. the cams 65 and66 is also providedwith a gear 7;, and the gear :71 at each seaming station meshes with a spur gear 72 which is fixed. to the, depending member. 19 on the.

bout ninety-tour. degrees. Th m i to. The seaming roll will move, however,-.to

. is considerable distance between these high after thefirst operation'is finished, before the second operation begins.' One ofthe reasons -for this is to permit the support for the can to be lowered and the'ca'n removed from the machine for inspection between'the first and second operations thereon, itbeing underfor this purpose. j The seaming roll by the seaming spindle. The' cam roll is likewise rigidly supported by the spindle, but is adjustable relative there'- cross a side seam through a torsional twisting or yielding of the spindle shaft which carries the seaming'roll, In 'other words,

the s indle carrying the seaming roll is of co'nsi erable -length,. and is capable of yielding 61' twisting intermediate the ends thereof forthe purpose stated. The cam rolls and the seaming rolls are mounted on crank arms in order to obtain the proper swinging move-' ments of the seaming rolls ,and in order that the -operating spindles for the seaming rolls indicated by the line a), m, and operate up may be placed relatively close together, and also close to the chuck s indle. 7

It will be notedfrom 'ig. 5 that the seaming rolls are mainl in advance ofthepath of travel of the cen er of he chuck, whichis on the can end at points fully outside of the path of travel of the center of the chuck. All of the actuatingparts forithe seaming travel of the I brought close in toward the center of rotation ofthe closing machine; It is also by f location'of the actuating parts that the chuck 4 gether. The filled cans when received spindles may be placedrelat ively' close tofrom - a minimum.

, is rigidly supported Associated with each of the upper' chuck" rolls are this P same distance as the chucks in the closing.

machine.

By the arrangement above referred to, V where the chucks are close together, and move in a relatively small circular path, the, spacing of the cansduring closing is reduced to a stood, of course, that the machineis stopped. to the closingma'chine'islikewise reduced to spindles is a seating pad 83. This seating pad is carried by a spindle 84 which extends up through the sleeve .38 carrying and rotat ing'the chuck. The seatihg pad isyieldingly raised by a spring 85. It is forced downwardly by a cam 86. This cam 86 surrounds the sleeve bearing 19 in the upper frame, and

is keyed thereto so that said cam 86 is sta-' tionary. The cam 86 has a high place 87,

shown more clearly in Fig. 4 of the drawings. This high place 87 in the cam moves the seatihgpad spindle downwardly as the turret rotates, and the high point 87 is so positioned in the rotation q of the machine as to move the seating padv down and cause the can end i.

to be seated in the can body. prior to the raising of the' can into contact with the chuck: Thus it is that the canend is held clamped against the. upper end of )the. cangbody as thecanbody and end are raised into contact with the upper rotating chuck. The'upper turret 9is provided with upwardly extending brackets 88 which carry a ring-89. This ring 89 is located in a recessed portion formed" fnthe cam 86. .There are ball bearings between the ring 89 and the cam 86 F The plate 90 secured to theeam 86 overlies thisring. he purpose of this ring is to hold the cam properly positioned foractuating the seating ing for the cam engaging the ring 89 carried by the brackets 88 on'the upper turret 9.

the filling machine are-closely spaced, but From b W b ap that this when taken iiitothe, closing machine, they must be spaced a -suflicie'nt distance to pro- 'vide room for the actuating mechanism for: the seaming rolls. distance is considerabl greater than the spacing of the cans in the filling machine, and therefore, the cans have to be acceleratedon their way from the fillingmachine to thenclosing machine. ,This is accomplished in applicants ease by a'fejed drum 79 which shown in Figures 1 and-1 I ofthe drawings. This drum is provided with a spiral thi'ead 8O which-is preferably shaped. so as to bring about the'necessary spacing tithe cans as they are delivered to theme- ",ceiving turret 81. This receiving turret is provided with pocketstg into which the filled cans are fed, and .thesepockets of the receiving turret for the' filled'cans are placed the construction permits the turret to rotate freely, and holds the cam against any upward. movement as {it actuates the seating pads.

I The downward thrust of the cam on Y the seating pads'is caused bytheroller bear-' setting of the turret. There is another high 1 point 91 on this cam 86 which operates to forcethe seating pads downward at another p'ointin the'rotation. of the closing machine.

The purpose of-this high point-91 is to eject or'force the canafter it is closed, off from the.

chuck. This occurs at'a point in the'travel of the seaming stat'on where the can is fully closed and is ready i chinei J L Mounted on the rbtat'ing sleeve 8 are two members- .08 and 109 which are bolted too be ejected from the magether and thus secured to the Sleeve. These members are provided with half molds 110.

aAt the upper face of each half mold there is a can end seat or centering mold 111. These half molds are centeredwith the axes of.the

rotating chucks and serve to round up and center the can body relative to the cooperating chucks. A

It is very essential that the axes of'the upper and lower chucks shall be in aline-' ment, and in order that this may beinsured,

"I have'provided means whereby the upper turret may be angu-larly adjusted on the supporting sleeve 8 therefor. The opening in the turret 9 at the lowerend thereof islarger' than the sleeve 8, and located in this opening is an elongated collar 8*. ,This collar is keyed to the sleeve 8 so that it rotates With ,the sleeve 8. The collar 8 at the lower end thereof is provided-with a fiange8. The

. 45 with the lower chucks.

extreme lower end of the upper turret 9is recessed to receive this flange 8 This flange '8" is provided with recesses .8. Pins 8 mounted in the'lower end of the turret project .into these recesses 8. The recesses 8 are of considerably ,greater width than the pins. As shown in the drawings, there are two pins, and; two separate recesses therefor, one

for each. A threaded bolt 8 is located'in the V flange and has threaded connection therewith. There are two bolts 8 one for each pin, but these bolts arelocated onopposite sides of the pin circuniferentially of the flange, or substantiallyso. Each .bolt is provided with a head 8 to which a wrench may be applied for turning the bolt in or out. By turning in on onebolt and releasing the other, the turret may be shifted angularly relative to the collar 8, and as the collar 8 is I ,I keyed to the sleeve 8, the upper turret'is'thusi angularly adjusted relative to the sleeve8, and as the sleeve 8 is secured to the lower turret, means is thus provided whereby the upper chucksmay belorought-into axial alinement The filled cans are received from'the closing machine gby the feed drum 7 9 as above referred to. They are fed along the support '112 therefor and are delivered to the pocket 82- of the assembling turret. The can ends are located in a can, stack holder 113. The ends are released oneat a time from said stack holder and are fed by a shaft ll lhav inga thread thereon, in a direction at right angle-site the travelof the filled canv (see'Fig.

. 1). Each half mold in the rotating turret.

. 81 is provided with a can end seat 115. The

. can end is moved along a supporting rail 116 by athread 117on theflshaft 114 and is seated? in this can end seat. The feed for the can ends is so controlled that no can end is fed unless there is a filled can going into the machine to be closed.

' The assembled can bodies and can ends are 455 carried by. turret into the, closing-machine and the half molds of the turret cooperate with the half molds in the closing machine in the rounding up of the. cam body, and the can end'seats associated with these half molds center the can end relative to ,the can body, so that the seating padcan force the, can end down-onto the can body. Suitable cooperat ing guides are provided for the guiding of the can body and can end, until thec an end 1s helil seated on the can body by the seating P canfrom' the upper chuck as above noted.

Thefclosed can then comes in contact with 122 carried-by and rotating with the lower turret" There are two take-away arms, first fter'the can end has been secured to the can body, the seating pad. strips the closed one of which and then the other comes into operation to remove the closed can. closed cam asitis moved by the take-away arm is brought into contact with a spring The"' pressed arm-123 which stops the spinning of p E the can due to' the stored momentum in the can. The can is .then moved so as to been; gaged by a printing roll 124 Where it is suitably marked. vThis marking mechanism forms no part ofthe present invention. The

markedcan passes'into a guiding chute 125 and is thus delivered from the machine.

' The turret 81 is rotated in timing with the main turret of the closing machine by a gear 126 which is secured tothe lower end of a shaft 127 carryinglthe turret 81 (see Fig. 2

This gear 126 meshes with agear 12,8 which is' secured to thelower turret and rotates therewith.

It is thought that the operation" of the can closing machine willbe apparent from the des'cription which has been given, and therefore, the movement of the can body and can end through the machine will only bebriefiy referred to.

' The filled cans are received from the filling machine by thefeed drum, and as they-are. v

moved along toward the assembling turret, they are spaced: from each other. This is brought about through the change in the pitch of the threadon the drum which will accelerate the filled can and bring about a end stack by the feeding mechanism which releases and feeds the can end forward when ever there is a filled ean to be closed. The can end is placed on the can end seat of the assembling turi'et, andthis is directly above the filled can. The can end seat on the closing
